I was playing around with an Arduino Nano Clone and programmed it via an USB <-> RS232 Adapter. At first it worked fine, but then the Board was not recognized. I was surprised because this Driver which Bricks the those fake FTDI chips has been withdrawn and FTDI changed their approach. At the time i was Running Win 8.1 and i couldn’t find a complete Fix which did work for me. This is what worked for me and Maybe it works for you too. I zipped the needed and modified Files the download is here.

2) Install the new (old v2.08.30 ) Driver. I modified the inf files to work with the 0000 PID (Right click on the unkown Device -> Search for th Driver on PC -> Browse the List of Devices -> Click on Storage Device and browse to the modified Drivers). Howto to Change the Inf Files in German ( Heise.de )

3) If Windows doesn’t want to install the unsigned Drivers you will need to Disable the Driver Signature Verification (Win + i -> click on the Power Button -> shift click on Restart -> Troubleshoot -> Advanced Options -> Startup Settings -> Restart -> Hit F7 when on the Dialog screen -> Repeat step 2). Here is a full Guide

I needed a new HDD for my NAS, the only criteria i had were:
– cheap
– 4TB
– from amazon.de

the cheapest 4TB HDD are around 28,6€/TB (geizhals.de) i found the Intenso
for 30€/TB which i found is a good price. Inside was the Western Digital WD40EZRX which costs 137€ (17€ more) at amazon. A downside of opening the case is losing your warranty. But you can sell the enclosure.

You can open the case by removing the top and bottom Plate. Use an old credit card and/or small screwdriver.
